Lipid-based nanocarriers as a strategy to improve delivery and enhance the efficacy of anti-infective compounds
Secondary Supervisor(s): Prof Tim Overton

Project Outline
Antimicrobial resistance (AMR) constitutes a major threat to public health worldwide. Bacteria employ numerous strategies to resist the action of antibiotics, including forming a sticky, glue-like protective matrix called biofilm.[1] Nanosized particles consisting of lipid bilayers, called liposomes, as well as lipid-coated nanoparticles, offer a solution to such delivery difficulties. These multi-compartment structures are capable of (co-)encapsulating and effectively delivering a range of anti-infective compounds to their bacterial target sites.[2, 3]
This project will explore the ability of lipid-based nanocarriers to improve anti-infective delivery and efficacy within range of different bacterial species in free-floating and biofilm form. The potential for synergistic antibacterial activity resulting from nanocarrier-mediated co-delivery of two anti-infective compounds will also be investigated.
Lipid-based nanocarriers loaded with anti-infectives will be produced using techniques such as microfluidic mixing, and characterised by dynamic light scattering and high-performance liquid chromatography. Microbiological testing of loaded nanocarriers will include minimum inhibitory concentration (MIC) testing to determine antibacterial efficacy, flow cytometry, and advanced microscopic imaging modalities to visualise nanocarrier-bacteria interactions.
The interdisciplinary project will be supervised by Dr Sarah Gordon (School of Pharmacy), an experienced formulation scientist in the use of lipid-based nanocarriers for anti-infective delivery, and Prof Tim Overton (School of Chemical Engineering), an expert on microbial physiology and antimicrobial resistance.
